Abstract (en)
[origin: EP2530757A2] There is provided a piezoelectric/electrostrictive element (1) comprising a piezoelectric/electrostrictive body (30) made of a piezoelectric/electrostrictive ceramic composition containing Pb (Ni 1/3 Nb 2/3 ) O 3 -PbTiO 3 -PbZrO 3 ternary solid solution system composition as the main components, and an electrode (10,10') disposed on the piezoelectric/electrostrictive body, wherein the ternary solid solution system composition is represented by the following composition formula: (where 0.005‰¤x‰¤0.03, 0.45‰¤y‰¤0.54, 0.58‰¤a‰¤0.91, 0.07‰¤b‰¤0.36, 0.02‰¤c‰¤0.08, 0.97‰¤±‰¤1.03, 0.97‰¤²‰¤1.03, 0.97‰¤³‰¤1.03, and (a+b+c=1.000)).
